形成された外装である。 In FIG. 1, reference numeral 1 denotes a capacitor element made of a metallized film or metallized paper wound, and metallicon parts 2a and 2b are provided on both sides. 3a and 3b are terminals connected to the metal contact parts 2a and 2b. 4a and 4b are insulating substrates that are connected to the separated portions of the terminals 3a and 3b and can be insulated.
As shown in FIG. 2, the insulating substrate 4a or 4b is made of a paper-phenol resin laminate, a paper-epoxy resin laminate, etc. with a thickness of about 1 mm, and is provided with a slit 5. This slit 5 has a similar shape to the safety device 6a or 6b, and is wide at the resin coating 7 and narrow at the metal wire 8. Copper foils 9-1 and 9-2 are laminated near both ends of the insulating substrates 4a and 4b, and these copper foils 9-1 and 9
The separated portion of the terminal 3a or 3b and the lead wire 8 of the safety device 6a or 6b are connected to the portion -2 by solder or the like. The safety devices 6a and 6b are arranged in the slit 5, are in contact with both end surfaces of the capacitor element 1, and are made of a flame-retardant metal wire 8 with a low melting point of 100 to 200°C and It consists of a resin coating 7 that melts near the melting temperature and covers a metal wire 8 with both ends exposed. 10 is capacitor element 1
It is an exterior that is formed by molding a resin such as polypropylene around the .

０の破壊、燃焼が防止される。 Since the present invention is configured as described above, when voltage is applied to the capacitor 11 from an external circuit and the capacitor element 1 deteriorates and generates heat, the safety devices 6a and 6b detect the heat generation of the capacitor element 1. Then, the metal wire 8 is melted, and as shown in FIG.
is disconnected. Since the safety devices 6a and 6b are disconnected midway, the capacitor 11 is disconnected from the external circuit and the current is cut off, causing the capacitor element 1 and the exterior 1
0 destruction and combustion are prevented.

この折り曲げ部は樹脂被覆が設けられておらず、
そのために、溶融しても樹脂が充填されず、確実

よれば、このような恐れがなく、金属線８を樹脂
被覆７の箇所で確実に切断できるので、保安装置
６ａ及び６ｂの誤動作を防止できる。 Furthermore, since the slits 5 provided on the insulating substrates 4a and 4b are similar in shape to the security devices 6a and 6b, the security devices 6a and 6b are connected to the insulating substrates 4a and 4b.
When connecting to the insulating substrates 4a and 4b, there is no need to bend the metal wire 8 and bring it into contact with the surfaces of the insulating substrates 4a and 4b. That is, for example, when a metal wire is bent and brought into contact with the surface of an insulating substrate, cracks occur in the bent portion, making it easy to melt at this portion.
This bent part is not coated with resin,
Therefore, even if the wire is melted, the resin will not be filled and the wire will not be disconnected reliably, and even if the wire is once melted and disconnected, there is a risk of a malfunction in which the wire is reconnected. According to the present invention, there is no such fear and the metal wire 8 can be reliably cut at the resin coating 7, thereby preventing the safety devices 6a and 6b from malfunctioning.
以上の通り、本考案によれば、保安装置の誤動

られる。 As described above, according to the present invention, it is possible to obtain a capacitor with a safety device that can prevent malfunction of the safety device and reliably prevent destruction and combustion of the capacitor element and the exterior.
